Dear Cosmin. You don't understand at all. Writing to current user registry as you said, doesn't require a hacker to break the protection. Even a 6 year child can break this protection by deleting the old user account and creating a new one. The trial will run again as new because in the new account created there is no information in the registry about written by my software. You should try this in your computer.
--- > Do you REALLY need to write to that file when a violation of any kind occurs? I don't understand what you want to say with this. Closing the application if it can't write to a protected file will convince my users to quickly remove my application from their computers since it can't be used. --- Cosmin Prund <[EMAIL PROTECTED]> wrote: > Do you REALLY need to write to that file when a violation of any kind > occurs?
